Application filed ay 18,1906. Serial No. 817,484.

, Be it known that l, l'V tLiAM E. (iituvEY, a citizen of the UnitedStaten, residing at Cleveland, in the county of (lt'vzihogu und 5 Stateoi ()hio, hove invented certain new and useful lilllH'UVLfilitliiiri inAir-(:irhureters;

and i do here'oy deelnre the folloi'iing to he a full, elem, and exactdesrrig'ition ol' the in vention, such as will enehle others skilled inthe n art to which it dpjitliillllri to nniltc and use the SRHIU.

For charging Hi! with on inliuinniuhle gun I have produced tlli improvedair-cnrhureter in Wllit'll the iiir is drawn by suction through A5 ithotly of hydroe-rirlmo liquid iind saturated with the fluid to render iteoiohustihle for use as H. motive power, and in the rhinos :ippendedhereto and in connection with the :lt'conipuvoting drawings 1 willpoint' out wherein my invention resides.

Referring to the drawings Figure l shows in. vertical longitudinalsertion a tank :iiri'iirhnreter einhodving in inqum'enient. Fig. 3 is Elhorizontal s etion, the greater portion of the hottonl perforated phiteheing broken uway and showing the lliirt ol' the tank divided intolongitudinal eoinpurl nienls and perforated pipes exttonling length oitil eiuzh eooipnrtnient ior d livering nir therein Fig: 1! its :1trunsveree st-ttion ol' the same looking toward the air-inlet pipes Fig-l is on end view showing the nir inlets nod means for closing tht-nr Ametal tank is divided h an upper ehiimher ii purluion into )Ul' 2 forcontaining the gusil'ving liquid ior elnirging the air. A perl'orutedplnte 23 form ti hottoni h'liiil'l' nhoui :in inch in depth, nod 40 this:spni'e is divided Irv pnrtitionu 4 into 21 pltlltllll) ot iongitudinnleonipnrtnients :3, each oi Whieh iu (overt-d h the periornted platev Apipe ti, which opens ill the end-well oi the innhni or near the top oithe gus- ('hnniher, passes through the peil'oriited pinto into eneh ol'the rompnrinienls und extends therein in n iei'l'oiided hrnnt'li T,which terniiniites in :1 will olihe lnnlt. short tuhi- S in the l;liii\'5 dividing pnrlition (HUMP/1H the supplrdnmr her \\'it h the gzist'hninheig end the l ved ol' the liqllitl through said luluis controlledh, u ll utinlilnlell vnlvc it, whi h determines the level of lhe liquidnhove the pell'oriili-d plottand which may be two or three inches, thevalve for this purpose being caused to be opened and closed by the riseand fall of the liquid above the perforated plate. Anysuitiihle floutmay he used; but I prefer to mount it in vertical guides 10, betweenwhich 6c it is caused to have it vertical movement on cross-guides 1 l,slidiihlefon the iertierlguiderods, so that the float will he in centralalinenient with the valve-stein to operate it, as *itttttl. A pipe 12enters the well of the gas 5 eluunher at the top thereof and oppositethe air-inlets and may lead to the cylinder of an explosive-engine, thesuction of the gas therein heing created by strokes of the piston. Inthis suction the air is drawn into the inlet of ent'h pipe at itsopening at the tank-wall, down and into the perforated pipe in eacheonipzirtnient beneath the perforated plate. These pipes will he lilledwith the liquid h vdroeiirhon to the level with the liquid in thegaswiunnher, and the till" will be drawn through this liquid and outthrough the perforations oi the pipes into and through the liquid intitt'll compartment, thence up through the perforations in thecoveringplate of the eoinpnrtnients,21nd through the liquid uhove theperforated plate into the giis-eluinilu-r. 'lhe advantage of U. separateeonipnrtinent lor eneh air-inlet pipe is that the nir is distrihntedunii'ornilv into the liq nid in each ronipiirtnient, so that the flow of:dr is slightly reliirded within the perforated pipes t llltl withineach compartment and is therehy caused to be thoroughly charged with thevapor oi lrvdrocarbon he tore it enters the giis-cluiniher.

'lhe nir-inieis I34 opening in the well, give the important advantage olhaving it plurality of iniperi'ornted tilt-(011dUt'lUJ'S and perioruledpipes iirrunged in ii group and of ('onl l l trolling the volume of:lll' to he g'iisiiied hy shin ting on one or more of theinlet-opei'iings nod neeessiiril 2| eorrespoinling nuniher oieonipin'tnienls to render the gns more or less I'il'll,tl nut he foundneeessiirv in its use, 1 and iorthis purpose :uh aii=inlet is providedwith it snilnhle rnt-oll', which [titty he 2t eluiined stopper H. Inthis particular the nil-roull'olletl tllF-illlllh' are also advantageousin nll'ording i he convenience for closing oil the iiir eonduits whenthe device is not in use, :ind thus prevent the evaporation of thehvdrociirhon and the production of gas.

partment may supply the required volume of air to a certain quantity ofliquid, yet I prefer to use a pair of perforated pipes in a courpartmentand to connect each pair as branch pipes to the end of an air-inlet pipeto in- :c crease the quantity of air delivered in each compartment.Obviously the devi e may be used with a forced air-feed instead ofsurtion;but I prefer the suction air-feed, because a forced air-feedwould require an air-punip I5 and means for connecting it with thewallopenings, In either feed the air is caused to ass in currents somedistance through the )ody of the hydrocarlmn within the perforated pipesand to pass therefrom into the hydrocarbon in the compartment and fromthence into the body of the hydrocarbon in the air-charged chamber.

1. An air-carburetor, eon'iprising a tank divided into an upper chamberfor contain ing a hydrocarbon liquid and a lower chamber for containingthe charged air, a perforated plate forming a bottom space, partitionswhereby said space is formed into a plu- 0 rality of longitudinalcompartments of which said perforated plate forms a cover, air-inletpipes opening at the tank-wall, each pipe extending down through saidperforated plate into one of said compartmems, closed at its inner endand having perforations the length of said compartment, atlmit-controlled feeding-valve connecting the liquid-supply and theair-charged chambers, and a suction-pipe connecting the air-chargedchamber opposite o the air-inlets.

2. In an air-carburetor, a tank divided into an upper chamber forcontaining a hydrocarbon liquid and a lower chamber for containing thecharged air, a perforated plate forming a bottom "space, partitionswhereby said space is formed into a plurality of lon itudinalcompartments of which said perforated plate forms a cover,air-inlctpipcs, each pipe extending down through said perforated 5onlate into one of said compartments and a pair of perforated pipes ineach compartment l l l,

connecting and extending as branch pipes from the end of each air-inletpipe, a heat: controlled feeding-valve connecting the liquid-suppfy andthe air('harged chambers, and a pipe for delivering the cl-iarged airvIt. In an air-car|iureter, a tank divided into an upper chamber forcontaining a hy drocarbon liquid and a lower chamber for containing thecharged air, a 1n-rforated plate forming a bottom space within saidlower chamhe' an air-inlet pipe entering said bottom space, and aperforated pipe connecting the end of said imperforated pipe and extending through said space beneath the )erfm rated plate, means for feedingthe liqui from the upper into the lower chamber and means for supplyinggas from the lower chamber 4. ln an air-carburcter, a tank divided intoan upper chamber for containing hydrocarbon and a lower chamber forcontaining the charged air, a perforated plate forming a bottom space inthe lower chamber, a plura ity of air-inlet pi 708 each comprising an imperforated branch opening at. the tank-wall, and a pair of perforatedbranches extending within and through said bottom space, means forexternally closing the air-inlets, means for controlling the supply ofgas from said lower chamber and means for feeding liquid from the upperinto the lower ehan'lber.

In an air-carlmrcter, a tank forming a chamber for-containinghydrocarbon and the charged air, a perforated plate forn'iing a bottomspace, partitions whereby said space is formed into a plurality ofloi'igitudinal compartments of which said perforated plate forms thecover, air-inlet pipes opening at the tank-wall, a pipe extending intoand through each compartment, closed at its inner end and havingperforations along the compartment, a suction-pipe connecting theair-charged ehamberwall opposite the air-inlets, and means for supplyingsaid chamber with bydrocarbon.

In testimony whereof I have signed my name to this specification in thepresence of two sul'iscribing witnesses.
